There is an older youtube video by David Berlinsky(sp) who talks about the impossibility of a cow changing into a whale. the TOE suggests that some land mammal had to have decided to become a water dweller and slowly change. This had to happen in a relatively small amount of time for evolution. Never mind the fact that there is no evidence of any animal ever changing kinds.
“the TOE suggests that some land mammal had to have decided to become a water dweller and slowly change”
I’ve never heard of that. I have heard of sea creatures emerging from the water.
Also changing from a land mammal to a aquatic mammal isn’t simply growing flippers and fins. (As if that is simple) It would also require a drastic metabolic change. No mammal could live in the water if it needed to resurface every 30-60 seconds. Also the animal would need to be able to cope with the rapid pressure changes and need a mechanism to prevent the bends from occurring.
“Never mind the fact that there is no evidence of any animal ever changing kinds.”
The Hawaiian Nene (bird) is clearly related to the Canada Goose but there’s been enough divergence that they are distinctly different species.
